Characterization of Antibiotic Resistance in Select Tertiary Hospitals in Uganda: An Evaluation of 2020 to 2023 Routine Surveillance Data

Antimicrobial resistance (AMR) is a public health concern in Uganda. We sought to conduct an extended profiling of AMR burden at selected Ugandan tertiary hospitals. We analyzed routine surveillance data collected between October 2020 and March 2023 from 10 tertiary hospitals. The analysis was stratified according to the hospital unit, age, gender, specimen type, and time. Up to 2754 isolates were recovered, primarily from pus: 1443 (52.4%); urine: 1035 (37.6%); and blood: 245 (8.9%). Most pathogens were Staphylococcus aureus, 1020 (37%), Escherichia coli, 808 (29.3%), and Klebsiella spp., 200 (7.3%). Only 28% of Escherichia coli and 42% of the other Enterobacterales were susceptible to ceftriaxone, while only 44% of Staphylococcus aureus were susceptible to methicillin (56% were MRSA). Enterococcus spp. susceptibility to vancomycin was 72%. The 5–24-year-old had 8% lower ampicillin susceptibility than the >65-year-old, while the 25–44-year-old had 8% lower ciprofloxacin susceptibility than the >65-year-old. The 0–4-year-old had 8% higher ciprofloxacin susceptibility. Only erythromycin susceptibility varied by sex, being higher in males. Escherichia coli ciprofloxacin susceptibility in blood (57%) was higher than in urine (39%) or pus (28%), as was ceftriaxone susceptibility in blood (44%) versus urine (34%) or pus (14%). Klebsiella spp. susceptibility to ciprofloxacin and meropenem decreased by 55% and 47%, respectively, during the evaluation period. During the same period, Escherichia coli ciprofloxacin susceptibility decreased by 40%, while Staphylococcus aureus gentamicin susceptibility decreased by 37%. Resistance was high across the Access and Watch antibiotic categories, varying with time, age, sex, specimen type, and hospital unit. Effective antimicrobial stewardship targeted at the critical AMR drivers is urgently needed.

infectious killers [2].The AMR burden fell disproportionately on sub-Saharan Africa and Asia, with Western sub-Saharan Africa experiencing the highest all-age AMR-attributable death rate at 27.3 per 100,000.[2].This coincides with the poor preparedness of the AMR surveillance systems and the paucity of AMR data in these regions [3].
As Uganda initiated its national AMR surveillance systems in line with the Global Antimicrobial Surveillance System (GLASS), a situational analysis revealed high levels of MDR due to MRSA (2-90%), ESBL (10-75%), and carbapenem-resistant Enterobacterales (CRE, 4-30%), as well as high resistance (>50%) to common antibiotics including penicillin, tetracycline, and cotrimoxazole [6].Uganda has since made significant progress in setting up its national AMR surveillance system, guided by a National AMR Surveillance Plan (NAP) based on the GLASS manual [7].Some of the initial surveillance data show that common pathogens including Enterobacterales and non-fermenting Gram-negative bacilli are resistant to third-generation cephalosporins, and there is emerging resistance to carbapenems [7].For instance, Escherichia coli resistance to ceftriaxone, imipenem, and ciprofloxacin was 52.7%, 18.8%, and 52% respectively, while Klebsiella pneumoniae resistance to the same antibiotics was 79.7%, 1.6%, and 53.8% respectively [7,8].This wide perspective of the country's AMR burden has been enabled by coordinated surveillance guided by the NAP, national governance structures, surveillance documents, and an expanded microbiology laboratories network [7].
Although the current national AMR surveillance data have informed the early AMR surveillance and AMR control efforts, a more comprehensive and well-structured profiling of the AMR burden to tailor the response efforts to the different levels of the health care system is still lacking.This evaluation therefore sought to conduct an extended profiling of the AMR burden and its variation with critical determinants including age, gender, sample types, and healthcare units at selected tertiary hospitals to fill the above gap.This information will be critical in informing and evaluating infection prevention and antimicrobial stewardship interventions aimed at preventing, slowing, and reversing the ascendance of the AMR epidemic in the country.It will also give insights into the performance of the AMR surveillance program and critical areas that need improvement.

Methodology
This was an analysis of the routine laboratory-based surveillance data collected between October 2020 and March 2023 from 10 tertiary hospitals, including nine regional (sub-national) referral hospitals and one national referral hospital in Uganda (Figure 1).
The country has a tiered healthcare system whose base is formed by health centers at the community level, followed by general hospitals, regional referral hospitals (RRH), and national referral hospitals.Regional referral hospitals are the first level, with specialists in the major fields of surgery, internal medicine, obstetrics and gynecology, and pediatrics.The national referral hospitals offer super-specialized healthcare with multiple specialists in different fields.Microbiology laboratory capacity has been gradually developed in the facilities over the past five years.At the time of data collection, all laboratories in the surveillance network were receiving continuous mentors in quality management systems using the strengthening laboratory management towards accreditation (SLMTA) and step-wise laboratory quality improvement process towards accreditation (SLIPTA) approaches.All the labs had applied for SANAS assessment for accreditation (Star 3-5).The country has a tiered healthcare system whose base is formed by health centers at the community level, followed by general hospitals, regional referral hospitals (RRH), and national referral hospitals.Regional referral hospitals are the first level, with specialists in the major fields of surgery, internal medicine, obstetrics and gynecology, and pediatrics.The national referral hospitals offer super-specialized healthcare with multiple specialists in different fields.Microbiology laboratory capacity has been gradually developed in the facilities over the past five years.At the time of data collection, all laboratories in the Qualified clinical and laboratory teams are deployed to collect and analyze the samples, and these undergo continuous in-service training and mentorship in diagnostic stewardship, AMR surveillance guidelines and protocols, bacteriology techniques, and laboratory quality management systems.Standard laboratory procedures are followed during sample processing.In-house reconstituted culture media are used for primary isolation, including 5% sheep blood agar, MacConkey, and chocolate agar.Bacterial identification was carried out using biochemical methods, including colonial appearance and Gram stain reactions.Culture media is quality controlled for sterility and ability to support growth using recommended American Type Culture Collection (ATCC) reference bacterial strains.Mueller Hinton agar (MHA) media performance and potency of antibiotic discs were assessed using Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, and Pseudomonas aeruginosa ATCC 27853 [9].Antimicrobial susceptibility testing (AST) was performed using the Kirby-Bauer disc diffusion method according to the updated CLSI M100, 30th, 31st, 32nd, and 33rd editions [10][11][12].
Specimens were collected from patients with various community-or hospital-acquired infections.The analysis included both GLASS priority (urine, blood, stool, urogenital, and cerebrospinal fluid (CSF)) and non-GLASS specimens, including pus and tracheal aspirates.Patient demographic and clinical details were collected using the standardized national microbiology laboratory requisition form, which accompanies all specimens to the laboratory.For purposes of this evaluation, we categorized the hospital units as "General units/wards", referring to those that provide care to relatively clinically stable patients such as outpatient, medical, surgical, and pediatric, among other wards, and "specialized units/wards", referring to units that provide care to critically ill patients, including high dependence, intensive care, and dialysis units.

Sample Size
The total number of patients sampled across the surveillance sites during the evaluation period was 14,484, which constituted the sample size for the evaluation.Results from blood, CSF, urine, pus, and tracheal aspirate specimens cultured during the study period were included in the analysis.

Statistical Analysis
Unique patient identification numbers and results were entered into the WHONET 5.6, AMR data management software [13].
For summary statistics, continuous variables were reported as means with standard deviation (SD) for normally distributed data or median and interquartile range (IQR) for non-normally distributed data.Categorical variables were reported as proportions in terms of frequencies and percentages.To derive the percentage of susceptible isolates for each pathogen-antibiotic pair, the number of susceptible isolates was divided by the total number of isolates tested against each antibiotic and multiplied by 100.Susceptibility was stratified by age, sex, specimen type, and hospital unit.Associations between susceptibility and these variables were established using the Chi Square test.The resulting percentages were reported with respective 95% confidence intervals (CI) and p-values.The three-month changes in the trends of susceptibility over the evaluation period were determined using linear regression analysis.Data analysis was performed in StataSE 15, R 4.2.2 software, and Microsoft Excel version 2020.At all levels of comparison, the level of significance was a paired p-value < 0.05.

Ethical Statement
The data used in the evaluation are part of the national AMR surveillance data extracted from the electronic laboratory records system as mandated by the Ministry of Health.The evaluation used de-identified aggregate data.There was no interaction with the patients.

Susceptibility of Isolates in General and Specialized Units
Susceptibility data are summarized in Table 2 (for general units) and Supplementary Table S2 (for specialized units).For Gram-negatives, data for ampicillin were only available for Escherichia coli, showing a remarkably low susceptibility of 4% for isolates from specialized clinics and 8% for general clinics.Escherichia coli susceptibility to the combination amoxycillin/clavulanic acid was much lower for specialized clinics (20%) compared to general clinics (56%).
Ceftriaxone, the only third-generation cephalosporin analyzed, also had very low susceptibility, ranging from 28% for Escherichia coli to 42% for 'other Enterobacterales' in general clinics, but did not remarkably differ from that observed in the specialized clinics.At 19%, meropenem susceptibility was remarkably low for Acinetobacter spp.isolates from specialized clinics.Notably, reduced susceptibility to meropenem was also observed for Klebsiella spp.isolates from the specialized clinics (70%).
Gentamicin, the only aminoglycoside analyzed, had susceptibilities just below 60% for Escherichia coli and Klebsiella spp.but higher at 71% and 65% for other Enterobacterales and Pseudomonas spp., respectively.Susceptibility to ciprofloxacin, representing the second-generation quinolones, showed low or modest susceptibilities ranging from 36% for Escherichia.coli to 60% for Pseudomonas spp.Among Staphylococcus aureus, only 44% were methicillin-susceptible, indicating a remarkable 56% MRSA prevalence.Susceptibility to erythromycin was also very low, at 34%.There were no data available for vancomycin.Among the enterococci, 66% were susceptible to ampicillin and 72% to vancomycin.

Antibiotic Susceptibility Variation by Hospital Units
Table 3 presents the distribution of bacterial susceptibility across various hospital units.There were significant variations in susceptibility to all tested antibiotics (p = 0.000-0.025)across the different hospital units, except for ciprofloxacin (p = 0.888), chloramphenicol (p = 0.109), meropenem (p = 0.136), and vancomycin (p = 0.64).The hospital units included the emergence department, gynecology ward, HIV clinic, maternity, outpatients' department, pediatric ward, and surgical ward.Notably, the susceptibility observed in the HIV clinic was higher than that in other units.However, the number of isolates from the HIV clinic was few (<30).

Antibiotic Susceptibility Variation by Age Group
Table 4 presents the distribution of bacterial susceptibility across different age groups, revealing significant variations in susceptibility patterns for various antibiotics across different age cohorts.Among individuals aged 5-24 years, the susceptibility to ampicillin resistance was 8% lower [OR = 0.54, CI = 0.33-0.88,p = 0.013] compared to those aged >65 years.Moreover, across all age groups, ampicillin susceptibility remained consistently low, below 20% for most age groups.In the 25-44 age group, there was an 8% lower susceptibility to ciprofloxacin [OR = 1.4,CI = 1.072-1.835,p = 0.014] compared to the >65 age group.Additionally, the 0-4 age group exhibited an 8% higher ciprofloxacin susceptibility [OR = 0.73, CI = 0.532-0.993,p = 0.045] compared to the >65 age group.Overall, the susceptibility to ciprofloxacin was below 60%.

Antibiotic Susceptibility Variation by Sex
Supplementary Table S3 displays the distribution of antimicrobial susceptibility by sex, revealing significantly higher susceptibility to erythromycin among males compared to females [OR = 0.75, CI = 0.595-0.941,p = 0.013].Susceptibility to other antibiotics did not vary by sex.

Antibiotic Susceptibility Trends
For Staphylococcus aureus, only gentamicin susceptibility demonstrated a marginal variation by quarters (p-value = 0.062).Gentamicin exhibited a decreasing trend (slope =  Notably, significant quarterly variation was observed for Klebsiella spp.susceptibility to ciprofloxacin and meropenem, indicating notable changes in susceptibility over time (p = 0.01 and 0.029, respectively).Ciprofloxacin susceptibility displayed a negative trend (slope = 0.0347), with approximately a 55% decrease in susceptibility by quarter (R-squared = 0.5503).Similarly, meropenem exhibited a negative trend (slope = 0.0427), with approximately a 47% decrease in susceptibility by quarter (R-squared = 0.4648).However, no significant variation was observed for ceftriaxone, chloramphenicol, gentamicin, and cotrimoxazole.
For Staphylococcus aureus, only gentamicin susceptibility demonstrated a marginal variation by quarters (p-value = 0.062).Gentamicin exhibited a decreasing trend (slope = 0.018), with approximately a 36.91%decrease in susceptibility by quarter (R-squared = 0.3691).There was no significant variation in susceptibility by quarter for cefoxitin, ciprofloxacin, tetracycline, chloramphenicol, and cotrimoxazole.

Discussion
We provide an extensive evaluation of AMR in Uganda, focusing primarily on the most isolated bacteria: Escherichia coli, Klebsiella spp., Acinetobacter spp., Staph.aureus, and Enterococcus spp.These ESKAPE organisms contributed 92% of the isolates, with susceptibility to specific antibiotics varying significantly among sample types and healthcare units.Remarkably reduced susceptibility was observed in all categories of the antibiotics, including the Access and Watch groups (AWaRe classification), with worryingly low susceptibility in the Watch category, more so in the specialized clinics.Similarly, resistance (reduction in susceptibility) was spread across all age groups, with resistance to certain antibiotics like ampicillin, ciprofloxacin, chloramphenicol, gentamycin, and methicillin varying significantly in certain age groups.Over the evaluation period, resistance was mostly linear except for ciprofloxacin, meropenem, and gentamycin, which showed a positive trend.Similarly, co-trimoxazole showed a slight positive trend for Klebsiella spp.and Staph.aureus with no significant change for Escherichia coli.A pronounced spike was observed in the E. coli, Klebsiella spp., and Staphylococcus aureus resistance between April and June 2021, the same timing of the COVID-19 pandemic peak.Notably, resistance against many antibiotics, particularly ampicillin and cotrimoxazole, was persistently high throughout the evaluation period.
Antimicrobial resistance to commonly prescribed antibiotics is widespread in the East African region, especially by Gram-negative bacteria [14].Earlier studies heralded AMR as an emerging threat in Uganda: Seni et al. found alarmingly high levels of MDR pathogens, particularly ESBL and MRSA, in surgical site infections at Mulago hospital as early as 2013 [15].Moreover, the epidemic was already occurring in the community;

Antimicrobial resistance to commonly prescribed antibiotics is widespread in the East African region, especially by Gram-negative bacteria [14].Earlier studies heralded AMR as an emerging threat in Uganda: Seni et al. found alarmingly high levels of MDR pathogens, particularly ESBL and MRSA, in surgical site infections at Mulago hospital as early as 2013 [15].Moreover, the epidemic was already occurring in the community; MRSA and ESBLs were highly prevalent in community acquired pyogenic abscesses presenting to Mulago hospital [16].Our evaluation demonstrated that there has been an increase in AMR compared to these earlier evaluations of surveillance data before and after the constitution of the NAP-AMR, both in terms of AMR prevalence and spread [6][7][8].The Gram-negatives exhibited high resistance to ceftriaxone, imipenem, ciprofloxacin, gentamycin, and chloramphenicol, and the high amoxicillin clavulanic acid resistance in Escherichia coli, presumably indicating a role for AmpC beta lactamases.Similarly, the high resistance to imipenem/meropenem by Escherichia coli, Klebsiella spp., and Acinetobacter suggested a high presence of carbapenamase producers.However, laboratory confirmation for ESBL and carbapenamase-producing organisms (CPO) was not done.The observed increase suggests that the stewardship actions being used are not having the desired effect, which requires immediate attention.
Among the Gram-positives, the very high prevalence of MRSA at 56% was particularly notable and comparable to the 53% found by Pius [17] from skin and soft tissue infections in western Uganda.Similarly, high rates of MRSA have been reported in Kenya (53.4%) [18] and Tanzania (43.3%) [19], suggesting that MRSA is endemic in Uganda and other East African countries.MRSA isolation from community-and hospital-acquired infections suggests continued emergence and transmission in both contexts, necessitating IPC and the promotion of rational antibiotic usage in both.Among the enterococci, 66% were still susceptible to ampicillin but, worryingly, vancomycin resistance was up to 24%.One study in Kenya identified no vancomycin resistance among clinical Enterococcus isolates [20].The World Health Organization listed the carbapenemase producers, ESBL, MRSA, and VRE, as critical and high-priority threats requiring urgent attention [21].The prevalence of the above resistance phenotypes was higher in specialized healthcare units like the ICU compared to the general units.Specialized units are characterized by extensive use of broad-spectrum antibiotics, invasive procedures, and the handling of patients with severe infections, which are predisposing factors for AMR [22,23].Moreover, resistance to all antibiotics in this evaluation significantly varied among the different healthcare units of the hospitals except for ciprofloxacin, chloramphenicol, cefixime, cefepime, and vancomycin.Therefore, context-specific interventions in addition to universal IPC and stewardship interventions are needed.
In this evaluation, ampicillin, ciprofloxacin, chloramphenicol, gentamycin, and methicillin resistance were significantly higher in certain age groups compared to the >65 age group.This indicates that age might be an independent risk factor for pathogens developing resistance to certain antibiotics.Hossain et al. also observed an age effect in urinary tract Escherichia coli resistance to antibiotic therapy [24].Escherichia coli resistance to amikacin, nitrofurantoin, and colistin was lower in the younger age groups compared to the >60 age group [24].Moreover, aging-related physiological, metabolic, and immunological changes are associated with specific changes in different body site microbiota, e.g., skin microbiota changed due to changes in skin sebum [25].The human microbiota has been deemed a reservoir of AMR due to its wide microbial genetic diversity, ecosystem for genetic exchange, and constant exposure to AMR determinants [26].This emphasizes that surveillance of antimicrobial resistance genes (ARG) in the human microbiota can be a source of information for AMR control strategies.On the other hand, there was less variation in AMR by sex, with only resistance to erythromycin being significantly lower in men than women.This contrasts Brandl et al. findings from the German national surveillance data, where men had a twofold higher incidence of resistant infections (2.3 for MRSA, 2.2 for carbapenem-resistant Acinetobacter baumannii, CRAB, and 1.7 for carbapenem-resistant Enterobacterales, CRE) and colonization compared to women [27].Men are favored in accessing health services because they hold the decision-making power and control of resources, factors that give them access to antimicrobials, a risk of AMR [28].Women, on the other hand, are more likely to attend local and free health facilities, which might prescribe antibiotics only when needed or when available [29].These findings show that gender-related effects on AMR are critical in efforts towards the control of AMR, which need to be urgently explored.
Resistance to several antibiotics including, ciprofloxacin, chloramphenicol, ceftriaxone, gentamicin, and erythromycin, significantly differed among the specimen types.This finding may have implications for empirical therapy for different infectious syndromes, as the infection may be due to microorganisms of the same species but different strains [30,31].However, few prior research efforts have focused on the effect of specimen type on AMR.Studies by Mwansa et al. showed that Staphylococcus aureus resistance to tetracycline was influenced by specimen type, being lower in urine compared to blood [32].Likewise, Escherichia coli isolated from sputum had higher resistance to common antibiotics compared to those isolated from blood and urine, except for urine, where Escherichia coli was more resistant to fluoroquinolones than that from sputum [33].Similarly, Salmonella enterica isolated from urine, blood, and stool had differing resistance to cephems, macrolides, phenicols, tetracyclines, and quinolones [30].The largest difference was observed with quinolones, to which the isolates from blood were less susceptible compared to those from urine or feces [30].It is plausible that the chemical and immunological properties of the different specimens that affect bacterial yield from the different specimens [34] might also alter the organism's response to antibiotic therapy.The GLASS also set priority specimens for surveillance based on infections of critical body systems that were showing alarming resistance to last resort antibiotics [35].The variation of resistance by specimen type observed in these studies emphasizes that for antibiograms to effectively inform AMR control, they need to be context-specific, including specimen type, organism, age, and others whenever possible.
We provide the first evaluation of resistance trends in bacteria predominantly isolated in Uganda.Positive trends in antibiotic resistance were noted for ciprofloxacin and meropenem for Klebsiella spp., gentamycin for Staphylococcus aureus, and ciprofloxacin for Escherichia coli, while cotrimoxazole showed a slight negative trend for Escherichia coli.The antibiotic resistance of most bacteria to the other antibiotics remained persistently above 30%, with none showing any negative trend.Selection pressure due to irrational use of antibiotics and the cloning of the selected resistant isolates likely underlie this persistently high and increasing trend in resistance against certain antibiotics [36].Notable was a pronounced spike in Escherichia coli resistance to amoxicillin clavulanic acid and gentamycin; Klebsiella spp.resistance to ceftriaxone, chloramphenicol, and gentamycin; and Staph.aureus resistance to cefoxitin and chloramphenicol during the COVID-19 pandemic peak.The Center for Disease Control reported a 15% increase in AMR between 2019 and 2020, largely driven by a breakdown in infection prevention measures and antibiotic prescriptions for supportive treatment of COVID-19 and bacterial co-infections [37].The increasing trends and persistently high resistance have implications for the empirical treatment of infectious syndromes [38], which is the commonest approach to treating bacterial infection in Uganda.Antimicrobial stewardship implementation strategies are urgently required to reverse the observed, but these would be more effective if they were targeted at specific situations or antimicrobials [39].
The greatest strength of our evaluation is that, unlike prior evaluations of AMR surveillance in Uganda, our evaluation presents a wide interrogation of the AMR surveillance data and considers how some critical parameters like age, sex, specimen types, and healthcare unit may influence the AMR surveillance outlook.This information is very critical to shaping Uganda's AMR surveillance efforts focused and effective.The evaluation was limited by the range of antibiotics tested and the range of pathogens considered, focusing on Escherichia coli, Klebsiella spp., Acinetobacter spp., Staph.aureus, and Enterococcus spp., which had large representative numbers for analysis.

Conclusions
We noted consistently high resistance across all WHO AWaRe categorizations of antibiotics, with increasing trends for certain antibiotics and significant variations by age, sex, specimen type, and hospital unit.The findings emphasize the necessity of transitioning to surveillance combined with infection prevention and effective antimicrobial stewardship strategies targeted at the critical drivers of AMR so as to reverse the ascending trends of AMR.Further, gender issues relating to AMR need urgent investigation, while molecular and genetic surveillance techniques, particularly those focused on ARG in the body microbiota, would improve stewardship interventions.
